The diagram below illustration the skeleton system of humans
Study it carefully and use it to answer questions 3(a) to 3(d).

(a) Name the parts labelled I to VI [3 marks]
(b) Mention one labelled part which represents a bone in the
(i)axial skeleton;
(ii)appendicular skeleton. [ 2 marks]
(c)Name the joint between
(i)II and VI
(ii)IV and V. [2 marks]
(dState three ways in which the skeletal system is important to the human body. [3 marks]

This question was attempted by many candidates and candidates did well in it. In part (a) candidates named the part labelled I to VII correctly however, few candidates lost marks because of wrong spellings. In part (b) some candidates took sternum as appendicular skeleton while humerus as axial skeleton. In part (c) candidates named the joint between (i) II and VI (II) IV and V correctly. In part (d) candidates stated ways in which the skeleton system is important to the human body.
The expected answers were as follows:
(a) Naming the parts labelled
I - sternum
II humerus
III pelvis/pelvic bone
IV femur
V tibia
VI scapula
(b )(i) Axial Skeleton
I1Sternum
(ii) Appendicular Skeleton
IIIIll/IV /V NIl named bone/humerus/pelvis/femur/tibia/scapula
(c) Naming the joint between
(i) II and VI - ball and socket joint
(ii) IV and V - hinge joint.
(d) Importance of the Skeleton
protects internal organs/soft delicate organ/named
gives shape to the body/forms the framework of the body
provides surface for attachment of muscles
provides lever for movement
it aids breathing
- aids production of red blood cells
- gives support.
